What is the maximum size of coarse aggregate (CA) in concrete.
What will be an ideal response?
The maximum size of CA is a function of various factors, such as the cross-sectional dimensions of the concrete component and the clear space between reinforcing bars. The larger the cross section, and/or the larger the clear space between bars, the greater the maximum coarse aggregate permitted. Typically, the maximum CA size in concrete is 3/4 in.
